A solid sphere is in rolling motion. In rolling motion, a body possesses translational kinetic
\( \mathrm{P} \) energy \( \left(K_{t}\right) \) as well as rotational kinetic energy \( \left(K_{r}\right) \) simultaneously. The ratio \( \mathrm{K}_{\mathrm{t}}:\left(\mathrm{K}_{\mathrm{t}}+\mathrm{K}_{\mathrm{r}}\right) \) for the
W sphere is :
(1) \( 7: 10 \)
(2) \( 5: 7 \)
(3) \( 10: 7 \)
(4) \( 2: 5 \)
